**Radicals** **Application Practice** Answer the following questions. Use Equation Editor to write mathematical expressions and equations. First, save this file to your hard drive by selecting **Save As** from the File menu. Click the white space below each question to maintain proper formatting. Hint: Pay attention to the units of measure. You may have to convert from feet to miles several times in this assignment. You can use 1 mile = 5,280 feet for your conversions. 1. Many people know that the weight of an object varies on different planets, but did you know that the weight of an object on Earth also varies according to the elevation of the object? In particular, the weight of an object follows this equation:, where _C_ is a constant, and _r_ is the distance that the object is from the center of Earth. 2. Solve the equation for _r_. 1. Suppose that an object is 100 pounds when it is at sea level. Find the value of _C_ that makes the equation true. (Sea level is 3,963 miles from the center of the Earth.)Use the value of _C_ you found in the previous question to determine how much the object would weigh in i. Death Valley (282 feet below sea level). ii. the top of Mount McKinley (20,320 feet above sea level). 1. The equation gives the distance, _D_, in miles that a person can see to the horizon from a height, _h_, in feet. Solve this equation for _h_. Long’s Peak in Rocky Mountain National Park, is 14,255 feet in elevation. How far can you see to the horizon from the top of Long’s Peak? Can you see Cheyenne, Wyoming (about 89 miles away)? Explain your answer.
